New Year's Day has arrived, and Xia Xiaofu's first birthday has also arrived.

Xia Xiaoqin specially ordered a birthday cake for Xia Xiaofu, and when Xia Xiaofu blew out the candles, his small mouth pouted, like the mouth of a little goldfish, and his appearance was extremely cute.

Xia Xiaoqin clapped her hands and sang a birthday song to Xia Xiaofu, singing and laughing, laughing and singing, when she was deeply emotional, her eyes were full of tears.

It's been a year since she came here, and she and Xie Chuan have known each other for almost a year.

Isn't it time to have an acquaintance anniversary or something?

But......

She didn't know where Xie Chuan was.

After celebrating her birthday with her family, Xia Xiaoqin returned to her room to write a letter to Xie Chuan.

She still maintains the habit of writing a letter a day, sometimes saving up a few days to send it together, and sometimes she misses it too much, so she will send it out what she wrote that day, and then call the army by the way.

On the tenth day after Xia Xiaoqin lost contact with Xie Chuan, Liao Jingwen went back to school.

She had lost a lot of weight, and after the baby fat on her cheeks faded, her line-carved features became more mean.

After Liao Jingwen returned to school, she was very low-key, helping classmates with difficult families in private, and whitewashing her actions in a silent way.

Liao Jingwen framed Xia Xiaoqin, and to put it a little lower, she was deceived by others and did a foolish thing in order to keep her father's love.

Xia Xiaoqin said that she had nothing to do with Liao Shiqing, but there were still some unbelievers.

They felt that if it really didn't matter, how could Liao Jingwen make a mistake.

Liao Jingwen used a subtle way to whitewash herself while quietly spreading the news of her father's disappearance.

Slowly, some kind classmates began to sympathize with Liao Jingwen.

Xia Xiaoqin knew that the Liao family had not found Liao Shiqing yet, not to mention how comfortable she was.

She concentrates on her studies and treats Liao Jingwen as air.

People with good deeds wanted to say a few words to Xia Xiaoqin and inquire about the news, but Xia Xiaoqin ignored them.

Ye Lechun felt that Xia Xiaoqin was going to suffer like this, and reminded Xia Xiaoqin: "Liao Jingwen has been pretending to be pitiful and innocent, and he must be holding back his big move, don't be tricked again." ”

"With you as my backing, I'm not afraid."

Ye Lechun gave Xia Xiaoqin a roll of his eyes: "It's about to be a winter vacation, it's really a moth, I'm afraid it will make you sick for a bad year." ”

Xia Xiaoqin is finally willing to face up to this problem.

She treats Liao Jingwen as air, but what if this air stinks?

Liao Jingwen can't be idle, right?

Then she will find something to do for Liao Jingwen!

Xia Xiaoqin wrote an anonymous report letter reporting that Liao Shiqing's cultural toy store was suspected of smuggling cultural relics.

On the third day after the report letter was sent, Xia Xiaoqin knew that Liao Jingwen had taken a week off work on the grounds of illness.

Xia Xiaoqin didn't need to inquire about the news, she knew that the report letter worked.

There is no Liao Jingwen in the school, and the air is fresh again.

Friday is Mr. Wu Yun's open class, in the class, Mr. Wu Yun asked everyone about their views on compound fertilizer.

In the 80s, most of the agricultural fertilizers were single-component.

For example, phosphate fertilizer, potassium fertilizer, micro fertilizer and so on.

Compound fertilizer is still in the research stage, how to prepare compound fertilizer, so that it is both nutritious and non-toxic, has become the most difficult problem for Wu Yun to overcome.

There are many types of nutrients in compound fertilizer, and the use of one compound fertilizer can be used to absorb at least two or more major nutrients for crops at the same time.

When it comes to compound fertilizer, Xia Xiaoqin's first thought is Shi Danli.

The advertisement of Shi Danli compound fertilizer has occupied the national station for many years, and it is very well-known, and it has also benefited farmers and uncles by virtue of its excellent quality.

During the farming season, farmers and uncles have an extremely high demand for chemical fertilizers.

On Xia Xiaoqin's way home from school, she often saw the extended truck parked on the side of the road, with uncles and aunts putting an old blanket on their shoulders and a towel around their heads, unloading fertilizer from the truck one by one.

Once, an uncle's fertilizer bag was hooked on the truck, and after the fertilizer bag rotted, the fertilizer was sprinkled on the ground like a miniature pearl ball.

The uncle who was carrying the fertilizer hurriedly lay on the ground to pick it up, and the wind was blowing, Xia Xiaoqin was disgusted by the choking smell of the fertilizer, but the uncle was like protecting a treasure, and carefully dispersed the fertilizer with his bare hands.

This scene was fixed in Xia Xiaoqin's mind for many years, and later she studied chemistry and deliberately understood the reason why compound fertilizer was made into granules.

After the compound fertilizer is made into granules, the hygroscopicity becomes smaller, and it is not easy to agglomerate and get wet, which is not only convenient for storage, but also convenient for spreading fertilizer.

At present, the chemical fertilizers with separate ingredients on the market are still in the form of powder, and it is a new idea to make them into granules.

The students were all speaking enthusiastically, and Xia Xiaoqin also raised her hand.

Wu Yun nodded at Xia Xiaoqin and asked her to express her opinion.

Xia Xiaoqin talked about the benefits of making the finished product into granules.

In her final summary, Xia Xiaoqin said: "We should not only consider the composition of compound fertilizers, but also the storage and quality of the compound fertilizer. To put it more simply, it is to ensure that the fertilizer does not deteriorate during the shelf life. ”

Wu Yun nodded thoughtfully: "The shelf life is a good proposition, there will be a waiting period for market reaction after the new fertilizer is put on the market, and we must ensure that the formula can stand the test of time."

But the hardest problem now is that we haven't found a balance between the various ingredients.

Xiaoqin, do you have an idea? ”

As soon as Wu Yun said this, the eyes of the classmates turned to Xia Xiaoqin.

Of course, Xia Xiaoqin has an idea.

When she was learning about chemical fertilizers, she read a book that can be called a divine book, "150 Kinds of Agricultural Compound Fertilizer Formula and Production".

Xia Xiaoqin just flipped through a few pages with curiosity at that time, and didn't see the end from the beginning, but she remembered all the pages she had read.

High-quality compound fertilizer can benefit the farmer's uncle, how can Xia Xiaoqin hide her privacy?

Xia Xiaoqin straightened her chest and said in a loud voice, "I want to apply to join the research group." ”

Wu Yun knew that Xia Xiaoqin could surprise her, and immediately agreed!

After class, the news that Xia Xiaoqin had crossed the level to join the research group quickly spread, and the students remembered that she was in the Institute of Chemistry and preached about food additives in front of thousands of classmates.

"Is Xia Xiaoqin a chemistry genius?" Someone asked.

People who have such doubts in their hearts have begun to pay attention to Xia Xiaoqin silently, the research progress of compound fertilizer and the use of food additives in Hongfu Food Factory.

High-profile is not Xia Xiaoqin's original intention, but it is already high-profile, Xia Xiaoqin thinks it is better to do something to improve her personal popularity, and add some gimmicks to the Guixiang brand that will be put into production of new products.

On the third day after Xia Xiaoqin joined the research team, after reading through the existing information of the research group, she wrote a formula of the ratio of water-soluble all-yuan compound fertilizer and multi-long-acting compound fertilizer.

Verification of the effectiveness of the formula is not a one-day result, but Xia Xiaoqin's writing of the two-ratio formula was quickly spread.

Is Xia Xiaoqin a chemistry genius?

Most people who have doubts have the answer in their hearts.

There are also people who are waiting for the results, but this does not prevent Xia Xiaoqin from becoming famous.

Because of the people who paid attention to Xia Xiaoqin, they pulled out the Hongfu Food Factory, and everyone bought the products of the Hongfu Food Factory with the idea of picking and doubting, and they all fell in love with the novel and rich taste.

The spicy strips and dried tofu with food additives are so delicious!

A week later, Liao Jingwen, who was anxious, returned to school and suddenly found that Xia Xiaoqin had become a celebrity in the school!

Liao Jingwen can't stand such a contrast!
